| description | The embodiment of the utility model relates to the technical field of display, and discloses a light-emitting structure, a backlight module and a display device. The light-emitting structure comprisesa substrate and at least two light-emitting elements which are arranged on one side of the substrate and electrically connected in series, and further comprises a packaging shell which is fixed to one side of the substrate and surrounds the light-emitting elements; the fluorescent powder is filled in a cavity formed by the packaging shell and the substrate; the dimming unit is dispersed in the fluorescent powder; wherein the state of the dimming unit can be adjusted, so that emergent light of each light-emitting element can be modulated. According to the technical scheme provided by the embodiment of the utility model, emergent light rays of the light-emitting elements which are arranged in series can be modulated, so that brightness adjustment of areas corresponding to the different light-emitting elements of th |
